Cadence Virtuoso UMC 180nm devices not rendering properly when layout is generated from schematic?

01 November 2017 1 3K Report

I'm using Cadence Virtuoso with 180nm UMC. Individually, the layout for each device in the UMC library loads perfectly.

After I create a new schematic and use the UMC devices to create, say, an inverter, the layout generated from that schematic has the transistors with displaced poly masks. Anyone having any idea what might be causing this?

Merge the display.drf file of UMC180 and if not working then remove the UMC180 library and freshly update the cds.lib file with UMC180 library.
